Effect of the incorporation of antagonistic plants on the parasitic activity of the root-knot nematode Meloidogyne hapla in a greenhouse carrot crop
A trial was conducted at the Centro de Investigaciones y Asesorías Agroindustriales (CIAA) of the Universidad Jorge Tadeo Lozano, Chía (Cundinamarca) under greenhouse conditions to assess the effect of incorporating fresh above-ground material of seven plant species (Tagetes zipaquirensis, T. erecta, Brassica cempestris. Bidens pilosa, Rufa graveolens, Taraxacum officinale and Ricínus communis) on the yield and commercial quality of a carrot (Daucus carota) crop var. Mokum, on the population density of Meloidogyne hapla and on the intensity of root-knotting of carrot. No significant differences were detected in the biological yield of carrot plants, but commercial average production obtained from plots.treated with R. graveolens and T. officinale were the highest (3070 g.m·2 and 2270 g.m·2) and significantly different from the control plots (1090 g.m·2). Final average population densities of infective secondstagejuveniles [J2] of M. hapla were significantly lower in the plots treated with R. communis, T. officinale, B. campes tris and T. erecta (65-130 Jj100 g of soil) than in the control plots (435 J2/100 g of soil). Significant differences were detected between rootknotting intensity of control plots (5.0 knots per root tip) and the averages of other treaments (1.9-2.6 knots per root tip).

En el Centro de Investigaciones y Asesorías Agroindustriales (CIAA) de la Universidad Jorge Tadeo Lozano, localidad de Chía (Cundinamarca), se llevó a cabo un ensayo bajo condiciones de invernadero para evaluar el efecto de la incorporación de material vegetal fresco proveniente de siete especies de plantas (Tagetes zipaquirensis, T. erecta, Brassica cempestris, Bidens pilosa, Ruta graveolens, Taraxacum officinale y Ricinus communis) sobre el rendimiento y calidad comercial de un cultivo de zanahoria (Daucus carota) varo Mokum y sobre la densidad poblacional del nemátodo del nudo de la raíz Meloidogyne hapla y la intensidad de la nodulación asociada con su establecimiento sobre plantas de zanahoria. No se encontraron diferencias significativas en cuanto al rendimiento biológico de la zanahoria, pero los tratamientos con R. graveolens y T. officinale mostraron la mayor producción de zanahoria comercial (3070 g.m·2 y 2270 g.m·2) con diferencias significativas respecto al testigo (1090 g.m-2). Las densidades poblacionales finales de juveniles infectivos [J2] de M. hapla fueron significativamente más bajas en los tratamientos con R. communis, T. officinale, B. campestris y T. erecta (65-130 J2/100 g de suelo) que en el testigo (435 J2/100g de suelo). En la nodulación se encontraron diferencias significativas entre el testigo (5.0 nudos/ápice de zanahoria) y los demás tratamientos (1,9-2,6 nudos/ápice de zanahoria).
